Description

Hello, I have a project that has three apps in it right now (and more on the way.) The apps
do build on each other in that the second app requires things in the first and the third app requires
things in the second, etc. Perhaps not a wise idea but it breaks down in to how the model works.

In any case I had a need of a filter that converted numbers like 50000 in to 5g0s0c - 100 c -> 1s 100s -> 1g
I found documentation saying that you could load custom templates and filters but nothing really
saying how to do that.

By looking at code it looks like I create a "templatetags" dir in my app dir (with init.py and all)
and put a file in there that defines the new filter.

Then in my templatetags dir I create a module. This module will contain a function that is the filter
an then contain a line that declares this filter to the rest of the framework:

# Now we have this function to make it truly useful we register it as a filter
# thus it can be used in our html template files directly as <9000>|num_to_gold
#
django.core.template.register_filter('num_to_gold', num_to_gold, True)

Now in the templates that need this filter I put at the top:

{% load items.helpers %}

then I use the filter. When I do this and call it from the dev server (ie: django-admin.py runserver ... )
it works fine.

Now, when I try to call this via the mod python server it fails.
Removing the {% load items.helpers %} from the template and it works.

The failure message is a bit befuddling:

There's been an error:
